    Greetings All -

    What is your favorite repair method for a trap lever pivot detachment as shown in the attached photo?

    Barb, what exactly is the problem? Is this a middle pedal that goes down and shifts to the left to lock? Did the screw it pivots on break?

    This is the sustain pedal trap lever.  The failure is in the spot welds that hold the pivot assembly to the trap lever.

    I will use a steel-reinforced epoxy (like JB-Weld Cold Weld) unless someone has another suggestion that is tried and true.

    I've never had much luck with epoxy on something like that. If it's a Yamaha, I'd try to get a replacement. Otherwise I'd probably try to through-bolt it.

    I have run across this a couple times on Yamaha P22s. One time I ended up replacing it from Yamaha, and one time I successfully put in bolts through the rod. The hardest part was just accessing the area, as there is very little room to work.

    I've found that if you remove the upper part from the base first, the pin that it rocks on is a carriage bolt threaded at the end and held with a small hex nut, then it's pretty easy to remove or reinstall the base. (It helps not to be too tall)
